  • Return highest number found in an array of strings

    - by Mdd
    I have an array of objects. The objects have a property called level that is a string which contains a number and is in consistent format. I am trying to find the highest number and return just that one but I seem to be blocked as far as how to proceed from my current code. Here is a fiddle to my current code: http://jsfiddle.net/6sXYR/ Here is my JavaScript: var myArray = [ { color: 'blue', level: 'L1' }, { color: 'red', level: 'L1' }, { color: 'green', level: 'L2' }, { color: 'yellow', level: 'L2' }, { color: 'purple', level: 'L3' } ]; for (var i = 0; i < myArray.length; i++) { console.log( myArray[i].level.substring(1,2) ); }; The result I am trying to get is to return just the number '3' from the example above. The highest number may not always be in the last object in the array, but it will always be in the format of L#.

    In the following markup on a page I want to extract out the following and put them in seperate variables. 1- In the onclick attribute get the value after the "ProductID" and put it in its own variable. "ProductID" So in this case it would be 318 2- In the onclick attribute get the value after the "Orig_price" and put it in a variable, "Orig_Price" So in this case it would be 22.95 3- In the onclick attribute get the value after the "width" and put it in a variable, "width" So in this case it would be 330 4- In the onclick attribute get the value after the "height" and put it in a variable, "height" So in this case it would be 300 <a href="javascript:void(0);" onclick="window.open('/BulkDiscounts.asp?ProductID=318&ProductCode=' + escape('LB30X40ES') + '&Orig_Price=22.95', 'Discounts', 'scrollbars,status,resizable,width=330,height=300');"><img src="/v/vspfiles/templates/100/images/buttons/btn_quantitydiscounts.gif" border="0" align="absmiddle"></a>

  • How to add multiple series in highcharts synchronously

    - by leonlong
    I tried to add multiple series in highcharts synchronously, but the response time is very slow. It took almost 3-5 seconds to display the charts. Here is part of the code. while(chart.series.length>0){ chart.series[0].remove(true); } chart.addSeries(series1); chart.addSeries(series2); chart.addSeries(series3); chart.addSeries(series4); chart.addSeries(series5); When I remain only one addSeries command, it response immediately, so I realized it may be the problem of add multiple series in highcharts synchronously. Not so good at highcharts, so is there anyone could help me about this? Or maybe there is another way to do this, I am much appreciated.

  • .each or search function, how can I make use of those?

    - by Noor
    I have a ul list, with 10 items, and I have a label that displays the selected li text. When I click a button, I need to check the label, versus all the list items to find the matching one, when it finds that I need to assign the corresponding number. I.e. list: Messi Cristiano Zlatan hidden values of list items: www.messi.com www.cronaldo.com www.ibra.com label: Zlatan script (thought)procces: get label text, search list for matching string, get the value of that string. (and if someone could point me in a direction to learn these basic(?) stuff. tried to be as specific as possible, thanks guys! edit: really sorry for not being clear. the li's are all getting a class dynamically (.listitem). the links can be stored in an array or in a hidden field (or other ul thats hidden) it doesn't really matter where the links are.. $('.listitem').click(function() { $("#elname").text($(this).text()); $("#such").attr("href", $(this).attr('value')); }); I was trying that with the li's having values but I realized that li's can't have values.. thanks again!

    - by João Pedro
    I'm doing this interface where I have a lot of buttons that are just a li with a background image like this #menu ul.icons li.nove { background-image:url(images/edit-menu/icons/undo.png); background-size:contain; display:block; margin-top:29px; } <ul class="icons"> <li class="um"></li> <li class="dois"></li> <li class="tres"></li> <li class="quatro"></li> <li class="cinco"></li> <li class="seis"></li> <li class="sete"></li> <li class="oito"></li> <li class="nove"></li> <li class="dez"></li> </ul> I need to create a code where I change the background image of the button when the user clicks it, to show that button its activated, I just need to change url(images/edit-menu/icons/ to url(images/edit-menu/select/ and keep the same filename. I need a way to do this dynamically so I won't have to do it for each of the 10 buttons. Hope I was clear, thanks in advance

  • Analysis Services with excel as front end - is it possible to get the nicer UI that powerpivot provi

    - by AJM
    I have been looking into PowerPivot and concluded that for "self service BI" and ahoc buidling of cubes it has its uses. In particular I like the enhanced UI that you get from using PowerPivot rather than just using a PivotTable hooked up to an analysis services datasource. However it seems that hooking up PowerPivot to an existing analysis services cube is not a solution for "organisational BI". It is not always desireable to suck millions of rows into excel at once and the interface between PowerPivot and analysis services is very poor in my book. Hence the question is can an existing analysis services solution get the enhanced ui features that power pivot brings, withoout using powerpivot as the design tool? If powerpivot is aimed ad self service/personal BI then it seems bizare that the UI for this is better than for bigger/more costly analysis services solutions.

  • Stack Overflow like Watermarks in Forms

    - by Kaushik Gopal
    Hey people, I remember seeing a tutorial somewhere that talks of how to style your input forms in a more "usable" way. Essentially, you have a placeholder value and when you enter the input, it hides the hint so to speak. Now, just to be clear: I don't want the hint (placeholder value text) to disappear onFocus, but rather to go lighter when I first start typing something. Good e.gs: Check out the forms on Aardvark http://vark.com/. This is exactly how I wish to have my input forms. Our very own stackoverflow. When you try to ask a question, on clicking inside any input form, it doesn't hide the text right away. You see your cursor as well as the hint. but when you start to type, it hides the hint(I would prefer having it go to a much lighter shade rather than hiding all together, like above example). I remember very clearly reading a tutorial somewhere on the interwebz with this exact requirement, but darn forgot to bookmark it. Any suggestions/links?

  • Toggle two divs and classes

    - by kuswantin
    I have two links with classes (login-form and register-form) relevant to their target forms ID, they want to toggle. I have also a predefined 'slideToggle' function to toggle better. This is what I have tried so far: $('#userbar a').click(function() { var c = $(this).attr('class'); $('#userbar a').removeClass('active'); $(this).toggleClass('active'); $('#register-form,#login-form').hide(); //bad, causing flashy $('#' + c).slideToggle('slow'); return false; }); With this I have trouble with the flashy window, and to correctly toggle the active classes when another link is clicked, the other link should not have active class anymore. Additional problem is the link is dead on serial clicks. I have another try, longer one: $('#userbar a').click(function() { var c = $(this).attr('class'); switch (c) { case 'login-form': $('#' + c).slideToggle('slow'); $(this).toggleClass('active'); $('#register-form').hide(); break; case 'register-form': $('#' + c).slideToggle('slow'); $(this).toggleClass('active'); $('#login-form').hide(); break; } return false; }); This one is worse than the first :( Any suggestion to correct the behavior? What I want is when a link with class login-form is click, so toggle the form with ID login-form, and hide the register-form if open. Any help would be very much appreciated. Thanks.

  • Error when passing quotes to webservice by AJAX

    - by Radu
    I'm passing data using .ajax and here are my data and contentType attributes: data: '{ "UserInput" : "' + $('#txtInput').val() + '","Options" : { "Foo1":' + bar1 + ', "Foo2":' + Bar2 + ', "Flags":"' + flags + '", "Immunity":' + immunity + '}}', contentType: 'application/json; charset=utf-8', Server side my code looks like this: <WebMethod()> _ Public Shared Function ParseData(ByVal UserInput As String, ByVal Options As Options) As String The userinput is obvious but the Options structure is like the following: Public Structure Options Dim Foo1 As Boolean Dim Foo2 As Boolean Dim Flags As String Dim Immunity As Integer End Structure Everything works fine when $('#txtInput') contains no double-quotes but if they are present I get an error (for an input of asd"): {"Message":"Invalid object passed in, \u0027:\u0027 or \u0027}\u0027 expected.

Also, when I pass the same input with quotes directly it works fine.

  • Ajax success function firing before java class responds

    - by user1899281
    I am creating a login function with ajax and am having an issue where the success function (SuccessLogin) fires before getting an ajax response. I am running the code as google web app from eclipse and I can see when debugging the java class file, that the javascript is throwing an alert for the success response from the class being false before the debugger catches the break point in the class file. I have only been writing code for a couple months now so I am sure its a stupid little error on my part. $(document).ready(function() { sessionChecker() // sign in $('#signInForm').click(function () { $().button('loading') var email = $('#user_username').val(); sessionStorage.email = $('#user_username').val(); var password= $('#user_password').val(); var SignInRequest = { type: "UserLoginRequest", email: email, password: password } var data= JSON.stringify(SignInRequest); //disabled all the text fields $('.text').attr('disabled','true'); //start the ajax $.ajax({ url: "/resources/user/login", type: "POST", data: data, cache: false, success: successLogin(data) }); }); //if submit button is clicked $('#Register').click(function () { $().button('loading') var email = $('#email').val(); if ($('#InputPassword').val()== $('#ConfirmPassword').val()) { var password= $('input[id=InputPassword]').val(); } else {alert("Passwords do not match"); return ;} var UserRegistrationRequest = { type: "UserRegistrationRequest", email: email, password: password } var data= JSON.stringify(UserRegistrationRequest); //disabled all the text fields $('.text').attr('disabled','true'); //start the ajax $.ajax({ url: "/resources/user/register", type: "POST", data: data, cache: false, success: function (data) { if (data.success==true) { //hide the form $('form').fadeOut('slow'); //show the success message $('.done').fadeIn('slow'); } else alert('data.errorReason'); } }); return false; }); }); function successLogin (data){ if (data.success) { sessionStorage.userID= data.userID var userID = data.userID sessionChecker(userID); } else alert(data.errorReason); } //session check function sessionChecker(uid) { if (sessionStorage.userID!= null){ var userID = sessionStorage.userID }; if (userID != null){ $('#user').append(userID) $('#fat-menu_1').fadeOut('slow') $('#fat-menu_2').append(sessionStorage.email).fadeIn('slow') }; }

  • Loop throught form inputs

    - by Victor
    I have a form with lots of inputs. I want to get each id and value and then put them in $.load method. I tried this: $("#form input").each(function() { var name = $(this).attr("id"); var value = $(this).attr("value"); $.extend(params, { name, value }); }); and then use $.load("script.php", params); But obviously it doesn't work. In params I have only one element "name". And I'm not sure I should use extend method too.

  • Pass dynamic data to mvc controller with AJAX

    - by Yustme
    How can I pass dynamic data with an AJAX call to an MVC Controller? Controller: public JsonResult ApplyFilters(dynamic filters){ return null; } The AJAX call: $(':checkbox').click(function (event) { var serviceIds = $('input[type="checkbox"]:checked').map(function () { return $(this).val(); }).toArray(); //alert(serviceIds); $.ajax({ type: 'GET', url: '/home/ApplyFilters', data: JSON.stringify({ name: serviceIds }), contentType: 'application/json', success: function (data) { alert("succeeded"); }, error: function (err, data) { alert("Error " + err.responseText); } }); //return false; }); Ideally would be that the filters would contain the serviceIds as a property For example like this: filters.ServiceIds. I got another filter for a date range and that one would be added like so: filters.DateRange. And server side get the filter as a dynamic object in the ApplyFilters()
